FIORELLI, Juliano; MORCELI, José A. B.; VAZ, Rodrigo I.  y  DIAS, Antonio A.. Evaluation of the thermal efficiency of roof tiles made of recycled long-life packaging. Rev. bras. eng. agríc. ambient. [online]. 2009, vol.13, n.2, pp.204-209. ISSN 1415-4366.

This paper presents a study of the influence of roof tiles made of recycled long-life packaging (brand-name IBAPLAC®) on the thermal comfort of zootechnical facilities. The research was conducted at UNESP's Experimental Campus at Dracena, State of São Paulo, Brazil. Four prototypes were built, each with an area of 28 m2. One prototype was covered with roof tiles made of recycled long-life packing material and three reference prototypes were roofed with ceramic tiles, ceramic tiles painted white and fiber/cement tiles (Brasilit®), respectively. Black globe thermometers and dry and wet bulb thermometers were installed inside the prototypes. Temperatures inside the structures were recorded in the Summer of 2006/2007 over a 90-day period. A descriptive statistical analysis was made, based on the mean values of black globe temperature and humidity index, radiant thermal load and temperature-humidity index of the period. The results obtained indicated that the thermal behavior of the recycled tile was similar to that of the ceramic tiles.

Palabras clave : ambiance; roofing; thermal environment indexes.
